Zusammenfassung:	1389259 Recovering flavouring substances TOBACCO RESEARCH & DEVELOPMENT INSTITUTE Ltd 3 July 1972 [6 July 1971 31 Jan 1972] 30975/72 Heading C6E Flavouring substances combined in the off gases from the fermentation of a vegetable material with an alcohol producing yeast are adsorbed on acti- vated charcoal to be later desorbed and added to the same or a similar beverage. Sulphuretted compounds are adsorbed first and the charcoal containing them may be discarded. The vegetable material may be e.g. grape must, or grain, grain mash, or fruit pulp and the beverage may be beer, wine or cider. Desorption may be achieved by immersing the carbon in a small volume of the beverage or with steam, a gas or liquefied gas inert to the system, or ethanol vapour.
